I heeded advice that used ground coffee beans may add nutrients to house plants. Today, I noticed a few seedlings coming out of the used ground coffee beans, although I have no idea what kind of species. It means that the seeds have survived the near-boiling point of water during coffee brewing.
I left the coffee bag immersed in hot water in a carafe of my coffee maker for more than 30 minutes. The digital probe thermometer measured the temperature to be at 80 C, which is way above the safe-food internal temperature of 71 C. It means that the safe-food temperature may not be so safe after all, considering also the fact that a group of small Caenorhabditis elegans worms survived re-entry of space shuttle Columbia after its disintegration?
